I love this place!

Yeah, no one gets mad when there are misunderstandings, we just dig a little deeper till we understand or give up. Sometimes the answers are lost in time and can not be figured out.

For BR on that drawing, could the label been mis applied by the publisher and that should have been wearing the label for pre 1899 less than 213000? I deal with some illustrations from a Swedish company catalog and the part numbers go with a different illustration that you would think. I believe they use a different labeling convention that we are used to.
Take a look at that 1.00 Radius on the outside of the barrel, have you ever seen that on any US Krag? I only have Krags with serial numbers higher than 266XXX and have not seen that profile. Do your 1896s have it? I looked at official photos on the KCA page and they all have hand guards so I could not tell if earlier barrels have that feature.

Edit:
Looked at BR's last chart again that is not the price of the change but a decimal length! Was that a temporary change to boost velocity and pressure for the 2200 fps experiment? Unlikely. Massive repeated typos? Doubt it. One would expect the latest permanent change to be the basis for SAAMI drawings. The earlier dimension became the became the basis for SAAMI? If you asked me last week I would say implausible!

We are missing something and now I have no clue what it is.

If anyone has seen that radius on the outside of any Krag barrel please raise your hand.  It would be interesting but right now I am not sure what it would tell you.
